Implement Comprehensive Email Format Validation

Description

Task

Implement Email Format Validation

Acceptance Criteria

• Implement RFC 5322 standard email format validation regex
  Ensure email validation prevents registration with invalid email formats
  Add database-level unique constraint on email field
  Create unit tests covering at least 10 different email format scenarios (valid and invalid)

Summary of Work

Overview

This pull request implements a robust email format validation system for the JobIt application, enhancing user registration and data integrity through comprehensive email validation.

Key Changes

• Added advanced email validation utility in lib/utils.ts
• Created comprehensive email validation tests
• Implemented database-level unique email constraint in User model
• Ensured case-insensitive email handling

Validation Implementation Details

1. Email Validation Utility (lib/utils.ts)

• Comprehensive RFC 5322 compliant regex
• Supports multiple email format scenarios
• Handles:
  • Standard email formats
  • Quoted local parts
  • Subdomains
  • IP address domains
• Implemented length constraints
• Case-insensitive normalization

2. Test Coverage (__tests__/email-validation.test.ts)

• 14+ valid email test cases
• 15+ invalid email test cases
• Covers edge cases including:
  • Special character handling
  • Domain variations
  • Length constraints
• Verified email normalization

3. Database Constraints (models/User.ts)

• Added unique index on email field
• Implemented case-insensitive uniqueness
• Pre-save middleware for email normalization
• Custom method to check email availability

Acceptance Criteria Met

• ✓ Implemented RFC 5322 standard email format validation
• ✓ Created comprehensive test suite with 10+ scenarios
• ✓ Added database-level unique constraint
• ✓ Ensured case-insensitive email handling

Testing Approach

• Unit tests covering multiple email format scenarios
• Validation of both valid and invalid email formats
• Verified normalization and uniqueness mechanisms

Notes

• Requires Mongoose/MongoDB environment
• Assumes proper database connection configuration
• Provides flexible and secure email validation

Potential Future Improvements

• Add more granular email domain validation
• Implement email verification mechanism
• Extend validation for international email formats

Changes Made

• Implemented comprehensive email validation regex
• Added email normalization utility
• Created extensive test cases
• Added unique email constraint in User model
• Implemented case-insensitive email handling

Tests

• Validate multiple email format scenarios
• Test email normalization
• Verify unique email constraint
• Check invalid email rejection
• Test edge case email formats
